London's Metropolitan Police Service (MPS) has completed a 20-week study in a bid to more accurately predict whether specific gang members are likely to commit violence. The software, developed by Accenture, pulls data together from systems already used by the MPS and runs it through an analytics engine. It's looking at geography, past offenses, associations with other criminal and even social media postings. An MPS spokesman told the BBC that the system would record and analyze threats or negative comments made by gang members on social media, for example.
